Family History patients
Patients with a strong family history of pancreatic cancer or with a genetic syndrome that puts them at risk for pancreas cancer.
Patients who underwent surgery for pancreatic cancer and developed tumor recurrence after surgery
- Number of subjects with histological features of PanIN lesions assessed [ Time Frame: 1 year ]Distinctive histological features of PanIN within surgical specimens of our two study groups will be assessed by pathologists.
- Evaluation of clonality multifocal PanIN lesions [ Time Frame: 1 year ]Using microarray-based comparative genomic hybridization (aCGH) to evaluate the samples.
- Evaluation of Recurrence Mechanism in PDC [ Time Frame: 1 year ]aCGH will also be utilized to evaluate recurrence mechanism in a set of cases in which both original tumor and recurrence tumor was resected, allowing for clonal origins to be evaluated.
Biospecimen Retention: Samples With DNA
- Blood samples
- Specimens of tumors, pre-cancerous lesions, and normal tissue from patients who need to have endoscopy or surgery for diagnosis or treatment of tumors that develop
- Samples of urine and stool, and duodenal aspirates if an individual will be having an endoscopy
